Runtime: Node.js
npx -y @blockrun/mcp
claude mcp add blockrun -s user -- npx -y @blockrun/mcp@latest
{ "mcpServers": { "blockrun": { "command": "npx", "args": ["-y", "@blockrun/mcp"] } } }You supply: ~$5 USDC on Base or Solana in an auto-created wallet (pay-per-call), optional SOLANA_WALLET_KEY
claude mcp add satohub-blockrun-mcp -- npx @blockrun/mcp
A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
Last 30 days — to 2026-09-15, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.

blockrun-mcp v0.48.0 — a key can live in a file, and a 429 says when to retry
A key can live in a file, not just an environment variable. Write it to ~/.blockrun/.api-key and account mode picks it up — same directory the wallet already uses, and for the same reason that file exists: a stdio MCP server is launched by its client, and several clients make setting an environment variable awkward or impossible. BLOCKRUN_API_KEY still wins when both are present, mirroring how BLO
blockrun-mcp v0.47.0 — account mode stops guessing
Account mode stops guessing. 0.46.0 shipped API-key billing with one honest limitation: it could not tell you what a call cost or how much credit was left, so it printed a local estimate with a ~ and a dashboard link. The account API gained both signals today, and this release consumes them. blockrun_wallet action:"status" now reads the real balance from GET /v1/credits : Account: acme (ungated) S
blockrun-mcp v0.45.1 — give the context number its own card, not badge nineteen
The context number gets its own card instead of being the second of nineteen badges. 0.45.0 published the figure but buried it — a shields badge in a row with MIT License , TypeScript 5 and Node ≥20.19 , which are table stakes, next to the one number nothing else in the ecosystem publishes. It now sits directly under the install command as a card: the figure large, a reference unit that makes it m
blockrun-mcp v0.45.0 — publish the context-window cost, and shrink it
Every tool schema got smaller, and the README now tells you by how much. Installing an MCP server spends your context on every turn — the client loads each tool's schema into the model's prompt and re-sends it for the whole session, whether or not you ever call the tools. Package managers have shown install size for thirty years; almost no MCP server shows this. Now ours does: a 🧮 12.9K Context T
blockrun-mcp v0.44.0 — MCP Apps: Polymarket order card and wallet panel
Two MCP Apps: a Polymarket order card and a wallet panel. Hosts that implement the MCP Apps extension — Claude Desktop, claude.ai, VS Code, Cursor, ChatGPT — now render blockrun_polymarket_read previews and blockrun_wallet results as interactive cards instead of text. The order card shows the question, outcome, side, best quote in cents, estimated shares, notional, a per-order cap meter and the se
blockrun-mcp v0.43.0 — every paid tool asks before it spends; skills install; setup/debug/upgrade skills
Every paid tool now asks before it spends. Spend confirmation via MCP elicitation ( BLOCKRUN_CONFIRM_SPEND=on ) shipped in 0.25.0 wired into blockrun_image alone; the other thirteen paid tools — chat, video, music, speech, realface, search, exa, markets, surf, defi, rpc, modal, phone — reserved budget and signed the x402 payment without a word. Each now pauses at its budget gate with the estimated
